Figure 3 is a transverse vertical sectional view on the plane indicated by the line 3-3 of Figure 2.

The die employed in the present invention is of the usual form "consisting of the head ring 10 and the plunger 11, being mounted for rotary movement in the spinner head 12 and axially aligned with the mold 14: which is movable in the usual manner toward and away from the die by any conventional means, such as a foot pedal 15.

After the pot 16 has been formed by the rotation of the die through the medium of the spinner head, accompanied with the elevation of the mold, there is left at the outer edge of the pot adjacent the mold wall a thin film of clay which, in the ordinary procedure, must be disposed of by hand prior to the removal of the pot from the .mold. The present invention comprises means for mechanically removing this film and such means comprises scraper pins 17 extending slidably through the head ring 10 in the direction of the aXis of the die, these pins protruding beyond the lower face of the head ring to engage the top edge of the pot adjacent the peripheral wall of the mold.

The pins 17 are slid-ably mounted in the re d y head rin-g' but are carriedby-iadial bats-18 dispqse bnt p zofi the; head rin and 'P ect1ngf per1pherally beyond, thelatter ifor connectionw tli the ,postsll). which attheir' lower ends afre formediwithl c'ups 2O receiv',

As the product contained in the mold as-v sumes shape and the elevation of the mold cont nues, the posts 19 are raised in the bearings until the mold approaches the under face of the head ring, at which time the molding operation is complete. The'mold is then dropped with the result that the sprlngs 23 depress the posts and in so doing move the bars 18 down toward the head ring, the scraper pins at this time beingex- 9 0 tended from the bottom face of the headring. Then the rotation of the spinner head effects the cleaning operation at the upper edge of the pot where it adjoins the mold, the pins scraping the corner clean of the film of clay contained therein. By means of the set-screws25, the extent of projection I of the cleaning or scraping pins 17 may be determined. T

The invention having been described, what is claimed'as new and useful is:

1. A pot die for. use with a spinner head and a cooperating mold, the same being provided with scraper elements disposed adjacent the periphery of the mold at the upper .105

edge in one position of the die with relation thereto, the scraper elements being movably mounted in the die and automatically re- I foot bearing upon the mold flange in one.

tracted into inoperative position on the full depth of penetration of the die into the mold. I I

. 2. In combination with apot mold and a cooperating die, a scraper element carried by a the die and engageable in the upper corner formed by the molded product with the mold, the scraper element being mold-actuatedfor moving into inoperative position upon the full depth of penetration of the die into the slidably mounted in the'head ring for pro trusion beyond the lower face thereof and engageable in'the corner formed by the molded product with the mold, a postslid v ably mounted on the head ring and having a position of the latter, and operative connections between the post and the scraper ele- 'ment for retraction'of the latter beyond the lower face of the head ring upon certain relative positions of the mold and die.

4. In combination with a pot die and a cooperating mold, the latter having a peripheral flange and the former comprising a head ring and a plunger, a scraper element 'slidablymounted "in thehead ringfor pro- 7 trusion beyond the lower-face thereof-and engageable in the corner formed by the molded product with the mold, a post slidably mounted on the head ring and having a a foot be'aring upon'the mold flange in one position of the latter, and a bar secured to the post and overlying the head ring, the scraper element being carried by said-bar.

5. In combination with a pot die and a cooperating mold, the latter having a peripheral flange andv the former comprising a head ring and a plunger, a scraper element slidably mounted in the head ring for protrusion beyond the lower vrace thereof and engageable in the corner formed by the molded product with the mold, a post slidably mounted onthe head ring and having a foot bearing upon the mold flange in one position ofthelatter, and a'bar secured to the post and overlying the head ring, the scraper element having an adjustable mounting in said bar.

In combination with a pot die and a cooperating mold, the latter having a peripheral flange 'and'the former comprisinga a head ring anda plunger, a scraper element slidably mounted in the head ring for protrusion beyond the lower face thereof and engageable in the corner formed by the molded product with the mold, a post slidably mounted onthe head ring and having a foot bearing upon the mold flange inone position of the latter, a bar securedto the post and overlying the head ring, the scraper element having an adjustable mounting'in said bar, and a spring mounted upon the head ring and bearing upon the upper edge of the post.
